ELEC3885 is an open-source printed circuit board by cairnsynth, from the cairnsynth/ELEC3885_Digital_Sampler_PCB repository on GitHub. It is a 2-layer board of 138 × 81.5 mm with 41 parts on 68 nets, routed with 356 tracks and 39 vias.
It is built around the TEENSY 4.1 and SGTL5000XNLA3. Its parts include 14 capacitors, 9 connectors, 4 resistors, 4 switches and 3 ICs. It belongs with the NXP (LPC, Kinetis, i.MX RT) boards of this library.

A synthesizer/guitar hybrid. Somewhere between a MIDI guitar and a synthesizer. Not commercially viable. A time sink. A rabbit hole. An obsession. A mistake. An exercise in blind faith. A reason to tidy the shed.

This project was done as my thesis to obtain my master's degree in Electronics Engineering. The proposed system aims to adapt a model to match the frequency and distortion characteristics of guitar amplifiers.

The SGTL5000 sound chip finds its place beneath the Teensy. It is the 20 (21) pin version, as opposed to the 32 pin version used on the audio shield.
It measures 138 × 81.5 mm and has 2 copper layers, 1.6 mm thick.
41 parts, built around the TEENSY 4.1 and SGTL5000XNLA3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the cairnsynth/ELEC3885_Digital_Sampler_PCB repository on GitHub, at the commit this page was made from: the board is ELEC3885.kicad_pcb and its schematic ELEC3885.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask cairnsynth before reusing the design.
